You can report the results of Kruskal Wallis or Friedman test as follows: **A Kruskal Wallis test revealed a significant effect of Group on Value (**<​html><​img src="/​mimetex/​mimetex.cgi?​\small \chi^{2}"></​html>​**(2)=13.7,​ p < 0.01). A post-hoc test using Mann-Whitney tests with Bonferroni correction showed the significant differences between Group A and B (p < 0.05, r = 0.56) and between Group A and C (p < 0.01, r = 0.70)**.
